Keyed fixed door lock

ABSTRACT

A housing, mountable on a panel, provided with a stepped bore therethrough into which a slidable bar is positioned to extend beyond each side of the housing. One end of the bar is provided with a finger-grip handle so that the bar may be pushed and pulled through the housing into and out of a predrilled bore in a second, relatively movable panel. When the bar is pulled toward the user and out of the predrilled bore, a larger diameter section thereof abuts a step in the housing bore to prevent the bar from being completely removed. When the bar is completely pushed in, a sphere may fall into a fillet on the bar. Pulling on the bar lightly will cause the fillet to push the sphere out of the way so that the bar can be withdrawn. A flange or cam, which may be rotated by means of a key lock, may be so located within the housing that it can positively retain the sphere against the fillet in order to positively prevent withdrawal of the bar.

sum 1 95 3 PATENIEUA'PR 1 siis KEYED FIXED noon LOCK BACKGROUND OF THEINVENTION Houses and other buildings constructed and remodeled inaccordance with modern architectural techniques are being provided witha maximum number of windows and other lightadmitting devices. Modernliving habits have also given rise to a requirement that houses bewell-suited to indoor-outdoor" living. These facts have resulted in theconstruction of a large number of buildings having sliding glass doorswhich may be easily opened so that people and air can quickly and easilymove in and out of the building.

Unfortunately, the extended use of the sliding glass doors, as well asother openable fixtures such as large windows, marine hatches, etc., hasalso increased the vulnerability of such buildings or structures toillegal and/or undersired entry by humans and animals. Many of theclosure devices are susceptible to being quickly and easily jimmied openand, in fact, cannot be locked against being opened unless they are inthe fully closed position. In other words, the closure cannot be lefteven partially open for the passage of air without creating the dangerof unauthorized entry unless an additional locking device is provided.For the sake of simplicity, the remainder of this discussion will referto the wellknown sliding glass doors by way of illustration. Thus, theterms fixed panel" and movable panel will be used. However, the readershould bear in mind that the present invention and the problems which itsolves are not limited to such doors. In other words, the solutionsherein proposed by this invention for the problems now being discussedare equally applicable to the locking against relative parallel movementof any elements, whatever their natures or use.

The problems described above have resulted in the creation of a widevariety of supplemental locks or locking devices which will prevent thedoor from being jimmied open whether the movable panel is fully closedor partly opened.

Some of the supplemental locking devices employ a variety of springand/or thread systems. For example, some locking devices have beenprovided which basically comprise rods which are mounted between thedoor jamb and the rear end of the movable panel. Often, such rods may beadjusted to a variety of positions so that the panel may be locked in afully closed position as well as in some predetermined maximum openedposition. While these devices do prevent the movable panels from beingopened beyond a predetermined position, they do not fully preventunauthorized entry into the structure since, in the case of most suchclosure members, it is quite easy to manually lift the movable panelaway from its lower track, tilt it slightly away from the track, andremove it from the wall entirely. In other words, these devices can bedefeated by moving the panels perpendicular to their normal direction ofmotion relative to the fixed panel.

Other devices have been disclosed which comprise a base member which maybe mounted on a door jamb or other structure so that a slidable rod maypass into a hole formed in the frame of the movable panel. Some of thesedevices have been provided with spring-biased elements which tend todrive the slidable rod into the hole in the panel. The rod must bewithdrawn against the biasing force before the panels can be movedrelative to one another. If the spring should break, the rod may easilyslide out of the hole in the panel due to vibration, etc. Further, suchlocks have only presented a nuisance resistance value in that adetermined housebreaker can very simply cut a small hand-hole in theglass, reach into the building, and pull the rod out of the hole in thepanel. When this has been accomplished, the device is no longereffective to prevent relative movement between the panels.

In U.S. Pat. No. 3,695,657, assigned to the Assignee hereof, there hasbeen disclosed a novel slide lock device comprising a base fixturehaving a pair of upstanding ears through which a locking bar may beslidably moved between extended and withdrawn positions. The bar may beprovided with one or more fillets so that the shackle of a padlock canbe passed over the bar and between the upstanding ears to preventmovement of the bar.

In some applications, it is aesthetically undesirable to have a padlockmounted on such a locking device. Also, when the padlock is removed fromthe device for its normal day-to-day operation, a location must beprovided for storage of the padlock so that it does not become lostbetween uses. It will quickly be realized that if such a lock isprovided for each of many closures along the ground floor of a building,the storage of the required padlocks becomes a horrendous problem.

Consequently, although the slide lock illustrated in U.S. Pat. No.3,695,657 is satisfactory in many situations and provides several highlydesirable features which may outweigh any deficiencies which it may beconsidered to have, none of the prior art devices has proven to betotally acceptable. They do not sufficiently prohibit break-ins, arecostly, and/or are inconvenient to use because, for example, theyrequire additional structure, such as padlocks, to provide completesecurity.

Another disadvantage inherent in many of the prior art locking devicesis that they must be mounted in substantially predetermined positionsrelative to the door, thereby allowing the building owner little or nooption as to the placement of the lock. In other words, some of thesedevices require that they be mounted on the door jamb at the sides ofthe door, others at the top or bottom of the door, and others inrelatively predetermined locations. Preferably, such a device should bemanufactured in such a way that the building owner has complete freedomin selecting the mounting location to suit his own convenience. In otherwords, it might be desirable to mount the lock on the fixed panel, themovable panel, or the door jamb. Similarly, it might be desirable tomount the lock in a high position so that it can be reached only byadults or in a low position so that it can be reached by everyone havingoccasion to use the door.

Accordingly, it is necessary and desirable to provide a door lock of thetype described which can be mounted in nearly any position, is verycompact so as to be unobtrusive and difficult to attack, can bepositively locked to prevent unauthorized opening of the door, and canbe-locked in such a manner that only authorized persons are able tounlock it. Further, it is preferred that the device be lockable withoutrequiring a separate lock for which storage must be provided when it isdesired to leave the device in an unlocked configuration.

SUMMARY OF THE INVENTION The present invention may be embodied in adevice A from being pulled completely out of the housing by whichachieves each of the above-described desired results withoutcompromising the integrity of the primary function of preventingrelative planar movement between two parallel, closely adjacentstructures.

In its preferred embodiment, the present invention may be formed of arelatively small housing which may be suitably positioned in any desiredlocation in relation to the two relatively movable structures. In onecomparatively simple form, the device may be constructed of a housingformed by a pair of mating castings which cooperate to capture and holda keyoperated cylinder lock having suitable tumblers. On the inner endof the cylinder, a cam may be suitably fixed so as to be rotatable whena key is inserted in the cylinder to actuate a detent within thehousing.

In any of the various preferred embodiments, the detent may comprise asphere which may be actuated by the cam into contact with a suitablylocated fillet on a locking bar or rod which is slidably mounted andextends through the housing. Thus, when the cam forces the sphereagainst the fillet, the locking bar cannot be moved in any directionand, by forming it to be of suitable length to extend into the movablepanel, the movable panel can be fixed in position relative to the objectto which the housing is fixed.

By providing the fillet to be of rather shallow curvature, when the lockcylinder is turned so that the cam is not exerting a positive forceagainst the sphere, an operator pulling on the exposed end of the rodcan force the sphere out of contact with the fillet and to pull the rodout of a predrilled hole in the movable panel. Of course, the housingcould be mounted on the movable panel and the rod made to extend intothe fixed panel with essentially the same result.

A variety of ways to mount the device in such a manner that it cannot beremoved without substantial destruction to the door may be madeavailable by suitable configuration of the housing exterior. Thus, itwill be realized that apparatus embodying the present invention may beformed of a relatively simple construction which is small enough to beunobtrusive. Consequently, it can be mounted in nearly any position and,preferably, in a position in which it cannot be attacked effec tivelywithout substantially destroying the door.

Since the device is locked by means of a key which turns a cylinderfixed in the housing, there is no need to provide a special lock orpadlock whenever a positive lock is required and. consequently, there isno need to provide any storage for such padlocks when they are removed.Also, since the device does not require the use of springs, etc., it issubstantially maintenance-free.

Additionally, it is a relatively simple matter to provide a plurality ofcylinder-locks with the same or similar tumbler or disc combinations sothat a large number of the devices can be locked and unlocked by meansof a single master key and/or an individual key for each lock. Further,proper design of the housing dimensions will allow the rod to have alength sufficient to prevent lifting of one of the relatively movablestructures relative to the other so that, for example. the movable panelof a door cannot be lifted off its track and pulled perpendicularly awayfrom the fixed panel.

On each side of the fillet, the rod may be provided with a distinctdiameter. For example, the end of the abutment with a shoulder in thehousing. On the other hand, that portion of the rod which can passthrough the shoulder may be provided with a finger-grip knob thereonwhich will positively prohibit the rod from being pushed so farinto thehousing that it cannot be retrieved when it is desired to allow thepanels to move relative to one another.

It will become apparent to those skilled in the art from the abovedescription that the rod can be pushed through the housing and into thepredrilled opening in the opposite panel without further action beingnecessary to prohibit relative movement. On the other hand, when it isdesired to prevent unauthorized persons from pulling the rod out of thepredrilled opening, a key may be inserted into the cylinder and turned,thereby actuating the detent against the fillet to prohibit movement ofthe rod. When this is accomplished, even if a housebreaker should cut asmall hand-hole in the glass, he will still be unable to pull the rodout of the predrilled opening. Thus, the device increases the integrityof the area to be protected.

If desired, the bar may be provided with a pair of fillets; one may beused to lock the bar in the predrilled opening and the other to preventits being pushed into that opening when it is desired to positivelyprohibit unauthorized locking of the door.

The present invention presents a true advancement in the art of lockingdevices and should not be considered to be limited to the embodimentsdescribed and illustrated here since these are merely considered to bepresently preferred embodiments, while the scope of the invention isdefined solely by the claims.

DETAILED DESCRIPTION In order to more clearly understand the full importof the invention, it is necessary to discuss various embodimentsthereof. These embodiments will also clearly illustrate that theinvention is not limited to a single structure but includesa largenumber of distinctive forms. Regardless of the form, the purpose of thepresent invention is to provide a novel apparatus for preventingrelative movement between a pair of panels 11 and 13 as illustrated inFIG. 1. For the sake of this discussion, it will be assumed that panel11 is fixed and that panel 13 is movable and that both comprise panelsof a glass door. It is important to note, however, that either or bothof the panels could be movable and the structure which is to be lockedagainst relative movement could be any structure of a similar nature,i.e., relatively movable in parallel planes.

In any event, panel 13 may be provided with one or more predrilledopenings or apertures 15, 17 through which a rod or locking bar 19 maybe selectively extended depending upon the relative positions of thepanels. In the embodiment of FIG. 1, the locking bar 19 passes through ahousing 21 which may be suitably mounted in any desired position on thepanel 11. In this illustrated embodiment, the housing 21 may be providedwith a pair of bores 23 which are coaxially aligned with a pair ofcounterbores 25 so that a shoulder is formed between the bores and thecounterbores. Accordingly, the heads 27 ofa pair of machine bolts orscrews 29 may seat against the shoulder to hold the housing against thepanel 11 when the bolts 29 are threaded into the adjacent edge of thepanel.

Thus, with the housing 21 suitably fixed to the panel 11 and the bar 19extended through a coaxially located opening in the panel 13, relativemovement in parallel planes of the two panels is positively prohibited.

Many sliding glass door panels are provided with structural retainingbolts 31 near the corners thereof so that the panels can be fabricatedfrom independent frame elements. In order to allow the housing to bemounted in any desired position, it may be provided with recesses 33 oneither side thereof as illustrated in FIG. 2 so that clearance willautomatically be provided between the housing and any obstructionsuch'as the head of bolt 31. Thus, the device may be installed in nearlyany practical location relative to the panels and- /or the door jamb inwhich the panels are mounted.

In order to more Clearly illustrate some of the specific details of thisembodiment, FIG. 3 comprises a sectional view of the structure and showsthe rod 19 to have a first locking portion 37 which is of a diameter tofreely pass through a bore 39 in the housing. The bore 39 extendsthrough the housing and ends at a radial shoulder 41 which terminates atthe periphery of a bore 43 of reduced diameter. A second or guidingportion 45 of the rod is provided which is of a smaller diameter thanthe locking portion 37 such that it will freely slide through the bore43. Intermediate the sections 37 and 45 of the rod 19, a fillet 47 maybe formed for a purpose to be described. A review of the drawing willclearly illustrate that the rod 19 can be pulled toward the right untilthe side of the fillet adjacent the locking portion 37 of the rod abutsthe shoulder 41 and prevents further axial movement thereof.

On the outer end of the guiding portion 45 of the rod, a knurled knob 49may be suitably mounted, such as by threading or by being stakedthereon. When the rod 19 is pushed to the left, as viewed in FIG. 3, itsmovement will be limited by contact of the knob 49 with the surface ofthe housing 21. Consequently, axial movement of the rod relative to thehousing 21 is limited by contact of the rod with various portions of thehousing. Accordingly, when the rod is in the position illustrated inFIG. 3, the locking portion 37 will extend through a suitable predrilledopening in a panel, such as that illustrated at in FIG. 1. On the otherhand, when one wishes to allow the panels to be moved relative to oneanother, the knob 49 can be pulled to the right,-as seen in FIG. 3,until the large end of the fillet contacts the shoulder 41, therebyremoving the locking portion 37 from the aligned aperture.

In order to ensure the security of persons or property within an areabounded by the panels, it is desirable to provide appparatus by means ofwhich the rod can be locked in one position or the other so thatunauthorized persons cannot take action which would allow the panels tobe moved. In this embodiment, a sphere or detent 51 may be providedwhich is freely movable through a passage 53 which intersects bore 39.The sphere 51 is illustrated as being seated against the rod due to gravity, but it will be realized by those skilled in the art that it couldbe spring-biased against the rod, if desired. In manufacturing thehousing, the passage 53 may extend all the way to the periphery thereofso that the sphere 51 may 'be inserted thereinto just before the rod 19is mounted in the bores 37 and 43. Thus, the detent 51 is prevented frombeing removed from the housing The detent may cooperate with the fillet47 to lock the bar in the extended position shown or, if desired, maycooperate with a fillet 55 so that the bar can be locked in thewithdrawn position. Preferably, the fillets 47 and 55 should be formedin rather shallow configurations on the rod so that pushing or pullingof the latter will force the detent 51 away from the rod in the passage53 a sufficient distance to allow the rod to pass when positive lockingis not required. In other words, move ment of the rod will thus beinhibited, but not prohibited.

However, in order to prohibit this movement, if desired, a suitablylocated actuating cam 59 may be fastened to the end of a shaft 61mounted in a tumbler or disc cylinder 63 which may be actuated by anysuitable means, such as a key 65. The cylinder 63 may be centrallylocated within a bore 64 having suitable inner surfaces A and B machinedfor desired clearances.

The cam 59 and detent 51 cooperate in the manner illustrated in FIGS. 4and 5. In FIG. 4, the cam 59 has been rotated so as to positively lockthe sphere 51 against one of the fillets on the bar 19. On the otherhand, in FIG. 5 the cam 59 has been shown rotated to a position suchthat the bar 19 can be pushed or pulled through the housing and freedomof movement is ensured by the clearance between the cam and the sphere.

Thus this invention comprises apparatus for preventing relative parallelmovement between adjacent panels, in the form of a relatively smallhousing which may be suitably mounted in any location relative to themovable panel member. The device may be actuated to prevent persons onthe outside of the panels from operating them by pushing the locking barthrough predrilled apertures without actuating the cam against thedetent. On the other hand, persons on either side of the panel can bepositively prohibited from operating the panels. The locking cylindercan be key-actuated to rd tate the cam against the detent, asillustrated in FIG. 4. thereby forcing the detent against the selectedfillet in the bar to positively prohibit movement thereof.

In order to prevent removal of the cylinder 63, a set screw 71 may bepassed through a passage 73 in the housing 21. Preferably, the accesspassage 73 intersects the axis of bore 43 so that when the bar 19 isinstalled in the housing, there can be no access to the setscrew.

Since the housing can be mounted in any suitable location, such as at acorner of a panel, and since the in-' ternal workings thereof are notexposed to any normal tools, it can be seen that if the bolt heads 27are formed so as to comprise one-way bolts, the device is substantiallyimpervious. V

The provision of a lock which remains in the housing at all times forselective actuation allows the device to be quickly and simply operatedwithout requiring installation of a padlock or other device and thenecessity of providing a location for storing the padlock when it is notin use.

Referring now to FIGS. 6 and 7, an alternative embodiment of the presentinvention has been illustrated for use with the panels 11 and 13. Withrespect to this embodiment, those elements which are substantiallyidentical in function to those described with reference to FIGS. 1-3have been provided with identical reference numerals, each preceded bythe numeral 1. Thus, housing 21 is now described as housing 121, etc..and no further description thereof is necessary.

In this embodiment, a clip 114 may be provided which fits over the headof the structural bolt 31. The clip may be fastened to the end of thepanel 11 by any suitable means such as screws 116 which pass through theclip and through bores in the end of the panel. Extending perpendicularfrom the face of the clip, a plate 118 may be provided which extendsinto a slot or kerf 120 in the housing 121. Plate 118 may be formedintegral with or suitably fastened to the clip 114 so that there is nopossibility of relative movement therebetween. A plurality of apertures122 extending through the housing may be coaxially aligned with similarapertures in the plate. When the apertures in the housing and the plateare aligned, suitable roll pins 124 may be extended therethrough in themanner illustrated in FIG. 6.

The housing is thus effectively locked to the clip 114. In this manner.the housing 121 can be effectively and permanently fastened to the endof the panel 11 in such a manner that it also is impervious.

The cylinder 163 may be fixed within the housing 121 in the mannersimilar to that shown in FIG. 3 or, if desired, the plate 118 may extendinto a kerf 125 in the side of a cylinder as illustrated in FIG. 6.Thus, the plate 118 can serve the dual purpose of locking the housing121 to the end of the panel 11 as well as locking the cylinder 163within the housing.

Referring now to FIGS. 8 and 9, another embodiment of the invention hasbeen illustrated. In this embodiment, elements which are substantiallyidentical to those illustrated and described with reference to FIGS. 1-3have been provided with like identification numerals, each preceded bythe numeral 2. Additional discussion thereof is not necessary here. Inthis embodiment. the housing 221 may be formed from two mating portions210 and 212 which may, for example, be castings. A plurality of locatingapertures 214 may be formed in one of the sections of locating apertures214 may be formed in one of the sections and a like plurality oflocating pins 216 may be formed in the other. Thus, when the sections210 and 212 are put together, the pins and apertures will mate so thatthe castings will be properly aligned. Further, by providing theclearances between the pins and the castings to be relatively minimal, atight and substantially permanent fit of the two sections may beensured.-

In order to further facilitate the mating capability of the twosections, either or both may be provided with a lip 218 thereon whichcooperates with the peripheral edge of the opposite section, therebyensuring parallel movement when joining the sections and alsoprohibiting access to the juncture.

In this embodiment, the bore 264 in which the cylinder 263 is mountedmay be provided with a pair of opposed lips 220, 222 which may beinserted into cooperative kerfs 224, 226 formed in the edges of thecylinder 263 as illustrated in FIG. 9. Thus, when the sections 210 and212 are joined, the cylinder 263 will be fixedly held against axial orrotational movement in the hous- Also, the use of the mating portions210, 212 allows the detent 251 to be located in a passage 253 which doesnot extend to the periphery of the housing. Thus the integrity of thedevice is still further ensured.

If the bolts 229 are provided with one-way heads as previouslydiscussed, they will not only serve to fasten the housing in place onthe end of the panel, but will also, when thus threaded into the panel,serve to fasten the sections 210 and 212 of the housing together so theycannot thereafter be separated.

Thus it can be seen that the invention set forth in the claims of thisapplication may be embodied in a plurality of distinctive devices,various embodiments having been illustrated here merely for the purposeof disclosing various structures which may be utilized to mount thedevice or to mount portions of the hardware therein. It will be quicklyrealized by those skilled in the art that additional embodiments of thisstructure utilizing different detents, locking and detent actuatingstructures, etc., may be similarly provided without exceeding the scopeand intent of the invention. It is. of course, intended that all suchembodiments be included within the scope of the protection provided bythe claims. hereof.
